802.11n is a specification for wireless LAN (WLAN) communications. An addition to the 802.11 family of standards, 802.11n is intended to increase network speed and reliability and to extend the operating distance of wireless networks. Raw data throughput is expected to reach as much as 600 Mbps, or more than 10 times the throughput of 802.11g.

Nov 12, 2019 · The 802.11n standard specifies 300 Mbps theoretical bandwidth is available when using channel bonding. Without it, about 50% of this bandwidth is lost (actually slightly more due to protocol overhead considerations), and in those cases, 802.11n equipment generally reports connections in the 130 to 150 Mbps rated range. IEEE 802.11n is an amendment to IEEE 802.11-2007 as amended by IEEE 802.11k-2008, IEEE 802.11r-2008, IEEE 802.11y-2008, and IEEE 802.11w-2009, and builds on previous 802.11 standards by adding multiple-input multiple-output (MIMO) and 40 MHz channels to the PHY (physical layer), and frame aggregation to the MAC layer. 802.11-1997 was the first wireless networking standard in the family, but 802.11b was the first widely accepted one, followed by 802.11a, 802.11g, 802.11n, and 802.11ac. Other standards in the family (c–f, h, j) are service amendments that are used to extend the current scope of the existing standard, which may also include corrections to a Apr 22, 2020 · 802.11n served as the fastest Wi-Fi standard for five years before the 802.11ac (Wi-Fi 5) protocol was approved in 2014. 802.11ac offers speeds ranging from 433 Mbps up to several gigabits per second, which approaches the speed and performance of wired connections. 802.11n (Wi-Fi 4) The first standard to specify MIMO, 802.11n was approved in October 2009 and allows for usage in two frequencies - 2.4GHz and 5GHz, with speeds up to 600Mbps. 802.11n can operate on either the 5 GHz frequency at a theoretical maximum speed of 300 Mbps or on the 2.4 GHz frequency in "mixed mode" which will support systems only capable of using 802.11b or 802.11g, but it will slow the entire network down to the maximum speed of the earliest standard connected.

Also, for whatever reason, my 802.11n Atheros Mini-PCIe on my ASUS Notebook seems to go crazy with a 1% chance of a connection that works as it will keep saying identifying adapter or even if it connects, it doesn't seem to allow surfing. The specification in 802.11g was able to increase the maximum speed to 600 Mbps with higher bandwidth. 802.11n can operate on multiple frequency bands, 2.4 GHz, and 5.8 GHz and has backward compatibility with 802.11a/b/g. Pros of 802.11n. Very fast maximum speed (600 Mbps) Better signal range than 802.11g

802.11n Wireless Technology The C1100Z features 802.11n technology with 2T x 2R antennas which provides the ultimate solution: improved speed, reduced dead zones, and extended coverage. With data rates of up to 300 Mbps, the C1100Z provides stable and reliable wireless connections for high-speed data and multimedia delivery.

802.11n certification extends to higher data rates, and 802.11n overlays may be necessary if high-speed services are to be assured. But the concern that 802.11n access points were power-hungry – many on the market still exceed the 802.3af Power over Ethernet limits – is transient.
